DESK. ATTACHMENT.

To all whom it may concern:

Be it known that 1, JENNINGS Sco'r'r Mo- Specification of Letters Patent. Application filed March 27, 1907. Serial No. 364,932.

! formed with. a rigid portion 43 to which the COMB, a citizen of the United States, and resi- I dent of Dobbs Ferry, in the county of West- Chester and State of New York, have made certain new and useful improvements in Desk Attachments, of which the following is a specification, taken in connection with the accompanying drawings.

This invention. relates to desk attachments and relates especially to attachments for roll-top office desks by which a special top or table is provided of suitable height for use when a erson is standing, such: top being adapted or book-keeping and other purposes v and being arranged so as to be readily withclosed within the same.

Fig' 2 is a similar par- .tial View showing the attachment inelosed inthe casing. Fig. 3 is a similar view of a modified constructionin which the casing is built integral with the desk itself.

In't e illustrative embodiment of this invention shown in the drawings, adesk of the general roll-top type is'indicatcd, having the top 42 to j'which the side pieces 40 are attached' soas to'properly support the cap 41.. The casing 58, 59 may be secured upon the cap and rear of the desk in thc'position indicated i'n Fig. l by any desirec means, this casing having the curved passage 51, 52 'to accommodate the table sections when not in As shown in Fig. 1, this casing is substantially-in the form of an inverted tisJqo the ca and the back of the desk.

e table is preferably d ipprtingfrom the spirit front ledge 44 may be secured and a. flexible section secured to the upper part of the rigid section 43 and eon'lposed of a series of interlocking members 45 secured upon a flexible backing 49 of fabric .or other material. 'lhis upper flexible section of the table is preferably held in operative position by a-suitable stop or projection 47 formed on one of the members and operating in a groove in the passage, as indicated, and also by the stiffening member or bolt 48 engaging the guideway or groove 4-6 in these mern ers and the tHljtLCQl'll) rigid section. of the table. As indicated this bolt may be provided with a suitable operating. handle 50 or other operating means and when the table has been withdrawn into the 0 )erative position indicated in Fig. 1 this bolt in thrust backward preferably as the flexible section is withdrawn from the casing so as to. suecessively engage .the preferably undercut grooves in each of the interlocking members J so as to rigidlyhold them in proper relative position. lnstead of having these bolts operate in suitable grooves 46 at the lateral edges ol the table as' indicated in Fig. 5, they may be arranged in sii'nilarlyreinforced grooves in. the lower'l'acc of the table, preferably adjacent the lateral edges thereof, as.

indicated in Figs. 6, 7'and 8 In this case, the bolts 63 operate in the grooves preferably pro'vidcdwith the metallic reinforcing plate 65 and may be moved as described by the operatinghandles (54 at the proper time so as to rigidly hold the series of members forming the flexible section in proper positionwhile the table is used. The front or lowor e'dgc oi the table i )relerably supported by a pair of legs 54 having tips 55 of yielding ni'aterial which may be pivotally mounted to swing about the pivots 61 and be held in operative position between the alining pins 62, (56, as indicated in F'gs. 4, 9 and l(). The pin' 66 .may as indicated] be partly withdrawn or moved out of;thc path of the leg so as 'to allow the leg to. swing up parallel to the table into a position behind t w ledge front and securely in this position.

stiilening members being pulled forward; at the proper tiinp so as to allow' the flexible rear section.

Instead of having the casing detachable,

which is desirable for use with the standard may be built roll-top desks, the cas' integral with the desk' itse f, as indicated in Fig. 3, in which instance the casing 60 is a part of the desk and is provided with aria.

able assage's for the table 43 and also for the re ar sectional roll-top 56 of the desk 57.
